.To all 'whom `zit may concern.' l

Be it known that I, WILHELM GR1EssER,a citizen of the United States, residing at J oplin, in the county of Jasper and State of Missouri,have invented -new and useful Improvements in Metallic Railway-Ties, of which the following is a specification.

This invention relates to certain new and useful improvements in metallic cross-ties for railroads, and has for its object to produce a cross-tie which shall be simplein construction and strong and durable in operation, and by the use of which the rails may be readily and firmly secured in position and when so secured will be prevented from spreading.

In order that the invention may be clearly understood, I have illustrated thegsame in the rails secured on the tie.

accompanying drawings, in which- Figure 1 is a top plan view of my improved cross-tie. Fig. 2 is a view in side elevation, showing the rails secured thereon. Fig. 3 is an enlarged view, in end elevation, of the crosstie. Fig. 4 is a top planview illustrating a modified construction of tie. Fig. 5 is a view in side elevation of Fig. 4, but showing the Fig. 6 is a longitudinal sectional view of the modiiied tie with the rails secured thereon. Fig. l7 is an enlarged view, in end elevation, of the modified crosstie. vFig 8 is an enlarged sectionalv view on the line 8 8 of Fig. 6, and Fig. 9 is a similar view on the line 9 9 of Fig. 4.

' Referring now to Figs. 1, 2, and 3', the crosstie is shown as an integral .structure and is cast from metal, either iron or steel, and comprises a flat base 1 and a hollow cylindrical head 2, which is braced from the base at suitable intervals throughout the length of the tie by'means of webs 3. Near opposite ends of the tie are provided fiat seats 4,- each of which has aibraced overhang or tongue 5 for engaging one side of the base of each rail. Each of said seats is also provided ,opposite the tongue 5 with an oblong aperture 6, through each of which a similarly shaped head 7 of a bolt 8 may be inserted and turned to engage the under side of the seat 4, wherel by a clamping-plate 9 mafy be secured in contact with the other side o y to that engaged by the tongue 5 through the the base of the rail medium of a nut 10, screwed on said bolt. The side and a portion of the ends of each of the seats 4 extend down to the base 1, as indicated by the rectan ular portion 11 of Fig. 1, and saidseats are urther braced by means of lateral webs orflanges 12. The cylindrical head Specification of Letters Patent.

2 extends beyond each seatto the outer ends of the tie, as clearly shown in Figs. 1 and2, and serves materially to strengthen the cjonstruction of thetie and'prevent it from bending either transversely or vertically. .-13 indicates a web extending throughout the` length yof the tie except at the seat portions, which web connects the cylindrical head 2 and base 1 the parts thus described, with the exception of the clamping-plates and bolts, are formed as an integral structure, the tie as a whole being made in a single casting.-

Referring now to Figs. 4 to 9, I have shown atie comprising similar features of construction to the cross-tie above described, except that these figures illustrate a tie which is a pressed from sheet metal. In forming this modified construction of tie asheet of metal lis bent or pressed to form a circular head 14, from which extend in contact with each other web members 15, and-the metal is bent at right angles to these Vweb members, at 'the lbase thereof, to form flangedextensions 16,

.which form the base of the cross-tie as a whole. gether by bolts or rivets 17. Extending PATENT opinion.

The web members 15 are secured tofrom opposite sides of the circular head 14 to the outer sides of the base member 16 are triangular-shaped braces 18, located at suitable intervals throughout the length of the crosstie. circular construction 14 of the head is discontinued and the metal is pressed out to form fiat seats 19, having walls continuing down to the base member 16, as indicated by 2() in Fig. 8. Said seat 19 is located in a plane be? low that of the top of the circular head 1.4, as clearly indicated in Figs. 6 and 7, anda portion of said circular head on the outer side of said seat is undercut to provide an overhang or tongue 21 to engage one side of the base of a rail 22, mounted on the seat 19. Opposite Near opposite ends of the cross-tie the` each of the tongues 21 the seat 19 is provided with an oblong aperture 23, into which a similarly-shaped head 24 `of a bolt .25 may be inserted and turned toengage the under side of the seat 19 at each end of the cross-tie, whereby a curved clamping-plate 26 may be held into engagement with the opposite side of the base of the rail to that engaged by the tongue 2l through the medium of a nut 27, screwed on the bolt 25. Each of the seats 19 in addition to the walls 20 is braced by means of webs or braces 28, extending from the said IOO IOS y walls to the outer edges of the base memv ber 16.

Both constructions above described are in essential respects `the same, the differences being substantially such as are necessitated by the fact that one ofthe ties is cast and the other pressed from a sheet of metal. In both constructions, however, the circular head 2 or 14 appears as a salient feature of the invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A metallic crosstie comprising a flat base and a head or top circular in cross-section and provided near opposite ends with seats for the rails.

2. A metallic orosstie comprising a Hat base and a head or top circular in cross-sec'- tion and provided near opposite ends with a seatand an integral rail-engaging member.

3. A metallic railway-tie having a ilat base and a circular head or top connected to said base by a central. web member, said tie being provided near opposite ends of its top with seats for the rails and with integral rail-engaging members.

4. A metallic railway-tie comprising a lat base and a circular head or top connected thereto by a longitudinal web member, a seat for the rail formed near each end of' said tie, an integral tongue overhanging each of sind seats, and a bolt-hole formed in each seat opposite said tongue.

5. A metallic railway-tie made of a single sheet of metal bent upon itself to form a circular top portion, web members extending in right lines from said top portion, and flanged extensions projecting at right angles to said web members to form a base, said tie having a portion of its top near each end of the tie depressed and lattened to form rail-seats, and having its circular head cut away at the outer end of each of said seats to provide a rail-engaging member, and each of said seats being provided with a bolt-hole.

In testimony whereof I have hereunto set my hand in presence of' two subscribing witnesses.
